Health Promotion with Long-Term Physical Activity Program for Adults with Autism Spectrum Disorder.

Individuals with autism spectrum disorder (ASD) are at higher risk for developing common chronic diseases. Engagement in physical activity (PA) can prevent health issues; however, people with ASD are known to engage in lower levels of PA in comparison to their peers. This study evaluated the effect of a long-term, 12-month PA intervention on the fitness and quality of life of adults with ASD. A quantitative approach was implemented to assess participants' fitness, functional ability, quality of life, and participation in a range of PA classes at three different time points. Qualitative data were collected via in-depth, semi-structured interviews with three participants with ASD and three staff members. A total of 34 adults with ASD (mean age 39.76 + 7.27) participated in the quantitative part of the study. Approximately 53% of the participants exhibited perseverance and conducted adequate PA each month. Significant improvements were found in one fitness component and two quality-of-life components. Factors revealed for the program's success were the individuals' free choice of the PA classes and supporting people and a budget that tailored the project. Policymakers who plan health promotion programs for adults with ASD should consider long-term PA programs, with freedom of choice among PA modalities and schedules.

The effects of the Friendship Online Intervention Program on physical activity, substance abuse, psychosomatic symptoms, and well-being among at-risk youth.

INTRODUCTION: At-risk youth are those who are currently or potentially exposed to physical, mental, or emotional danger. The Friendship Online Intervention Program (FOIP) was created to encourage physical activity (PA) and reduce risky behavior among vocational secondary-school youth in Israel. We wanted to evaluate the effect of FOIP on PA, substance abuse, and psychological factors, including psychosomatic symptoms and well-being. METHODS: From October 2021 to June 2022, nonrandom sampling was employed to select at-risk youth from vocational secondary schools for participation in the FOIP. Before and after the intervention, questionnaires were administered to the intervention and control groups. The effects of FOIP were evaluated by univariate and multivariable analyses. RESULTS: The intervention (n = 103) and control (n = 77) groups showed similar levels of PA, cigarette smoking, and alcohol consumption at the beginning of the study. At follow-up, the intervention group showed a 57% increase in PA versus no change for the control group and decreased levels of smoking compared to the control group (p < .001). Similarly, in the intervention group, the number of psychosomatic symptoms decreased (effect size = 1.68) and life satisfaction increased (effect size = 0.86). Group assignment (intervention or control group) significantly predicted PA level, cigarette smoking, psychosomatic symptoms, and life satisfaction (adjusted R2 = .46, .20, .08, and .28, respectively) with participants in the intervention group showing more favorable results compared with the control group. CONCLUSIONS: FOIP was effective in increasing PA and decreasing risky behaviors among youth. FOIP may help at-risk youth build resilience and promote their physical and mental health.

Long-term outdoor recreation program for adults with intellectual disabilities: Feasibility and effects.

BACKGROUND: While people with intellectual disabilities tend to refrain from physical activity, outdoor physical activity programs increase motivation to engage in physical activity. METHOD: Eighty adults with intellectual disabilities participated in a 12-month outdoor physical activity program. Attendance was used to assess feasibility. Aerobic capacity (6-min walk test), lower extremity endurance (30-s chair stand), and mobility (timed up and go) were assessed at three-time points: before, during, and after the program. Six interviews were also conducted with six staff members and participants. RESULTS: The physical activity program was feasible, with all six groups completing the year-long activity. The six-minute walk and timed-up-and-go tests improved significantly. The qualitative analysis indicates the program's strengths (instructors' qualities and programs' social component) and weaknesses (dependency on weather and bureaucracy). CONCLUSION: Among adults with intellectual disabilities, a long-term outdoor physical activity program is feasible as a means for increasing aerobic capacity and improving mobility ability.

The Influence of Yoga on the Cognitive Function of People Aged 60 Years and Older: A Systematic Review.

Context: With aging, cognition declines, leading to functional limitations and a loss of independence. Yoga is a particular kind of physical activity that can have a positive influence on cognition in older adults, because it aims to improve physical skills and to enhance the ability to focus and to neutralize external mental stimulation. Objective: The literature review intended to evaluate the effects of different types of yoga interventions and to examine which cognitive functions were affected by them for healthy people aged 60 years and older. Design: A search of the terms "yoga and cognition" and "yoga and cognitive function" was conducted using the PubMed and EBSCO databases. For inclusion, an article must have: (1) included healthy participants aged 60 and above, (2) been an intervention lasting between one week and six months, and (3) been an RCT. Three reviewers independently assessed each study. Setting: The Academic College at Wingate, Israel. Participants: Out of 503 articles, only five met the inclusion criteria, and had in total 461 participants, 128 men and 333 women, aged 60 years and older. Interventions: Interventions in the studies lasted between one and six months. Yoga methods included Hatha yoga, Trataka yoga, Iyengar yoga, and Himalayan Siddha yoga. Outcome Measures: Methods and tools applied in the studies were compared. The outcome measures examining cognitive functions included working memory, executive functions, visual memory and processing, focus and attention, and reaction time. Brain physiology outcomes were also screened. Results: An analysis of the type of yoga method was conducted and is presented in terms of the length and frequency of each intervention, the tests applied, and the effects of each intervention. In three articles, with a total of 293 subjects, the yoga intervention groups showed significant improvements in the ability to perform various cognitive functions as compared to the control groups. In two articles, with a total of 168 participants, no significant improvements were found for any of the groups, and none of the articles reported a decline. Conclusions: The studies differed in the type of yoga, length of the intervention, and type of cognitive-function assessments, making results inconclusive. Nevertheless, based on the examined randomized controlled trials (RCTs), overall yoga may offer benefits to cognitive function. However, a greater number of RCTs with a larger number of participants and rigorous research methods are required to support this recommendation.

Should knee extension strength testing be implemented as a screening test for identifying probable and confirmed sarcopenia in older T2DM patients?

BACKGROUND: The accelerated loss of muscle strength and mass observed in older type 2 diabetes mellitus (T2DM) patients due to the combined effects of diabetes and obesity, greatly increases their risk for sarcopenia. Early detection and treatment of probable and confirmed sarcopenia is paramount to delay mobility disability. Using low handgrip strength cut-off points for the initial identification of sarcopenia according to the new European Working Group on Sarcopenia in Older People (EWGSOP2) guidelines may mask the presence of sarcopenia. Relative knee extension strength cut-off points using a simple hand-held dynamometer can assist clinicians in the diagnosis of probable and confirmed sarcopenia by possibly reducing false negative results. METHODS: A cohort of one hundred T2DM older patients (60% women) (mean age 74.5 years) mostly obese community dwelling older adults were evaluated for body composition by Bioelectrical impedance analysis (BIA), yielding appendicular skeletal mass index (ASMI) results. Patients underwent handgrip strength (HGS) and knee extension strength (KES) tests as well as functional ability tests. Prevalence of probable and confirmed sarcopenia using HGS and KES cut-off points were calculated. Pearson correlations were performed to evaluate the relationship between ASMI and limbs strength. A regression analysis was conducted to examine which variables best predict ASMI values. A multivariate analysis of covariance was performed to assess the effect of independent variables on KES and HGS. RESULTS: Using cutoff points for low KES identified 24 patients with probable sarcopenia and two with confirmed sarcopenia. Conversely, using the EWGSOP2 cut off points for low HGS, identified only one patient with probable sarcopenia and none of the patients with confirmed sarcopenia. CONCLUSION: KES cut-off points using a simple hand-held dynamometer can assist in the identification of probable and confirmed sarcopenia using EWGSOP2 cut off points for low muscle mass in a population of older T2DM patients for further analysis and early treatment. This is notably true in patients possessing high body mass index (BMI) alongside normal ASMI and HGS, potentially reducing false positive sarcopenia screening results.

Predictors of Future Walking Speed: A 12-Month Monitoring Program.

The purpose of the current study was to identify significant predictors of walking speed (WS) among community-dwelling older adults, as it is one of the most representative measures of functioning in their daily lives. Seventy-seven (24 adult men, 26 adult women, and 27 older-adult women) community-dwelling older adults (73.7 ± 4.9 years) performed two assessments, over a 12-month period. Several physical, cognitive, and psychological tests were performed, as well as assessing the preferred WS. Multiple linear regression, stratified by gender, was used to identify significant predictors of future WS. For the adult men, walking and functional performances at the first assessment predicted 71.9%; for adult women, reaction time, walking, and balance performance predicted 64.4%; and, for the older-adult women, fast walking and reaction time predicted 48.2% of the variance of future WS. Clinicians should consider including different exercises for each group of older adults to evaluate and preserve functional abilities.

Does Photobiomodulation Therapy Enhance Maximal Muscle Strength and Muscle Recovery?

Photobiomodulation has been shown to improve tissue and cell functions. We evaluated the influence of photobiomodulation, using a B-Cure laser, on: 1) maximal performance, and 2) muscle recovery after resistance exercise. Two separate crossover randomized double-blinded placebo-controlled trials were conducted. Sixty healthy physical education students (28 men, 32 women), aged 20-35, were recruited (30 participants for each trial). Participants performed two interventions for each experiment, with real lasers (GaAlAs, 808 nm) on three quadricep locations in parallel (overall treatment energy of ~150J) or sham (placebo) treatment. In the first experiment muscle total work (TW) and peak torque (PT) were measured by an isokinetic dynamometer in five repetitions of knee extension, and in the second experiment muscle recovery was measured after the induction of muscle fatigue by evaluating TW and PT in five repetitions of knee extension. There were no differences between treatments (real or sham) regarding the TW (F(1,28) = 1.09, p = .31), or PT (F(1,29) = .056, p = .814). In addition, there was no effect of photobiomodulation on muscle recovery as measured by the TW (F(1,27) = .16, p = .69) or PT (F(1,29) = .056, p = .814). Applying photobiomodulation for 10 min immediately before exercise did not improve muscle function or muscle recovery after fatigue.

Correlates of Early-Stage Frailty-Sleep, Fitness, Oxidative Stress, and BMI.

Frailty reflects a decreased reserve in multiple systems resulting from cumulative decline. Frailty markers should be identified as early as possible to attenuate the loss of reserve. The aim of this study was to identify potentially modifiable correlates of frailty in relatively healthy older adults. Volunteers (n = 122) were recruited from local councils and, based on gender and age, were divided into one group of men aged 77.0 (±5.3), and two groups of women, aged 68.8 (±3.6) and aged 78.4 (±3.4). Frailty was assessed by a Frailty Index. The examined correlates were: physical activity, physical fitness (predicted peak VO2), sleep quality, oxidative stress (hydrogen peroxide-H2O2) and depression. Both groups of women had poor scores on physical fitness compared to women's norms. In order to examine the contribution of each of the potential correlates to explaining the variance of frailty, stepwise regressions were performed for each group separately. Based on the results, none of the suggested correlates significantly explained the variability of frailty in the men. In the younger-aged women, predicted peak VO2 and sleep quality explained 22.4% of the variability of frailty. In the older women, Body Mass Index (BMI), oxidative stress and sleep quality explained 34.9% of the variance. It is possible that increased aerobic fitness and interventions for improving sleep quality in older, seemingly healthy women will slow down the frailty process. Further research is needed to assess potential correlates of frailty, and to initiate suitable interventions to mitigate the signs of frailty at an early stage.

The Effect of Balance and Coordination Exercises on Quality of Life in Older Adults: A Mini-Review.

The ability to control balance during activities of daily living (ADL) is impaired in older adults as a result of deterioration in the sensory systems (i.e., vestibular, visual, somatosensory), the cognitive system (central nervous system), and the musculoskeletal system. Consequently, many older adults face a risk of falling during their ADL. In most cases, falls and related injuries impair the quality of life and result in physical limitations, anxiety, loss of confidence, and fear of falling. Among a variety of fall prevention interventions, adapted physical activity programs have been suggested for improving balance control during ADL. These programs challenge the sensory, cognitive, and musculoskeletal systems while addressing balance constraints such as orientation in space, changes in direction, and the speed or height of the center of mass during static and dynamic situations resembling ADL. The above-mentioned elements can be dealt with through a combination of balance and coordination exercises that challenge the postural control systems in multiple dimensions-including vertical and horizontal changes of the center of mass, standing on unstable surfaces with a reduced base of support, and changing body directions. Consequently, such exercises require environmental information-processing. The combination of dual-task, function-oriented challenges while controlling balance stimulates the sensory and neuromuscular control mechanisms. Among older adults, these programs have been found to improve static and dynamic stability, as well as a number of aspects in the quality of life. Recently, they have also been found to improve cognitive functions such as memory and spatial cognition.

A Preliminary Study of Dual-Task Training Using Virtual Reality: Influence on Walking and Balance in Chronic Poststroke Survivors.

BACKGROUND: Stroke is a leading cause of death and disability in the Western world, and leads to impaired balance and mobility. OBJECTIVE: To investigate the feasibility of using a Virtual Reality-based dual task of an upper extremity while treadmill walking, to improve gait and functional balance performance of chronic poststroke survivors. METHODS: Twenty-two individuals chronic poststroke participated in the study, and were divided into 2 groups (each group performing an 8-session exercise program): 11 participated in dual-task walking (DTW), and the other 11 participated in single-task treadmill walking (TMW). The study was a randomized controlled trial, with assessors blinded to the participants' allocated group. Measurements were conducted at pretest, post-test, and follow-up. Outcome measures included: the 10-m walking test (10 mW), Timed Up and Go (TUG), the Functional Reach Test (FRT), the Lateral Reach Test Left/Right (LRT-L/R); the Activities-specific Balance Confidence (ABC) scale, and the Berg Balance Scale(BBS). RESULTS: Improvements were observed in balance variables: BBS, FRT, LRT-L/R, (P < .01) favoring the DTW group; in gait variables: 10 mW time, also favoring the DTW group (P < .05); and the ABC scale (P < .01). No changes for interaction were observed in the TUG. CONCLUSIONS: The results of this study demonstrate the potential of VR-based DTW to improve walking and balance in people after stroke; thus, it is suggested to combine training sessions that require the performance of multiple tasks at the same time.

The effect of circuit resistance training, empagliflozin or "vegeterranean diet" on physical and metabolic function in older subjects with type 2 diabetes: a study protocol for a randomized control trial (CEV-65 trial).

BACKGROUND: Treatment of the older diabetic individual comprises a therapeutic challenge. Currently little scientific evidence exists depicting the best approach to type 2 diabetes treatment in this growing sub-population of patients. The purpose of this study is to assess the effects of a modified plant-based Mediterranean diet ("vegeterranean" diet), circuit resistance training (CRT) and empagliflozin, separately or in combination, on body composition and physical function in older subjects with type 2 diabetes. The rationale for this study is to assess three interventions associated with a negative energy/caloric balance (increased caloric use in exercise, caloric restriction in the "vegeterranean" diet and caloric wasting by glycosuria with empagliflozin), their interaction and effect on body composition and physical function. METHODS: One hundred and twenty men and women ≥65 years of age with type 2 diabetes, and low levels of physical activity will be randomized (1:1:1 manner, gender stratified) for 10 weeks to one of 3 parallel arms: CRT consisting of 3 home sessions/week; ad-libitum plant-based Mediterranean diet (limited consumption of eggs, dairy and fish, avoidance of red meat and poultry) or empagliflozin 10 mg/day. After 10 weeks CRT will be added to the empagliflozin and diet arms for an additional 10 weeks. Allocation concealment and blinding of primary outcome assessors will be implemented. Efficacy will be determined by assessment of lean body mass, body weight, frailty and functional status, sarcopenia, HbA1c and quality of life questionnaires. Safety will be evaluated by routine monitoring of adverse events. This study was approved by the Tel-Aviv Sourasky Medical Center Institutional Review Board. DISCUSSION: The combination and comparison of these diverse interventions to metabolic control may lead to better understanding of their mechanism of action with potential clinical implications in older individuals. Also, this study will provide evidence of the effectiveness of these interventions on delaying the progression from diabetes to sarcopenia and/or frailty. TRIAL REGISTRATION: ClinicalTrials.gov PRS: NCT03560375 . Last registration date (last update): 06/06/2018. The trial was a-priori registered before actual recruitment of subjects.

The effect of a stability and coordination training programme on balance in older adults with cardiovascular disease: a randomised exploratory study.

BACKGROUND: Cardiovascular diseases are considered a leading factor in mortality and morbidity. The older adult population with cardiovascular diseases has a higher risk of falls as compared to a matched age healthy population. OBJECTIVE: To investigate the effect of stability and coordination training within a cardiac rehabilitation programme on fall risk in older adults with cardiovascular diseases enrolled in cardiac rehabilitation. METHODS: Twenty-six people with cardiovascular diseases (age 74±8) were divided randomly into intervention and control groups. The intervention group received 20 min of stability and coordination exercises as part of their 80 min cardiac rehabilitation programme, while the control group performed the traditional cardiac rehabilitation programme, twice a week, for 12 weeks. Balance assessment was based on three tests: the Timed Up and Go, Functional Reach and Balance Error Scoring System, which were measured twice before the intervention, once following the intervention and once four weeks after the termination of the intervention. A two-way analysis of variance (group × time) with repeated measures was performed to examine differences between groups and between assessments. RESULTS: Seventy per cent of participants in the intervention group adhered to the programme, with significant improvement post-intervention in the Timed Up and Go (p < .01) and the Balance Error Scoring System (p < .05) with no changes among the control group. DISCUSSION: Stability and coordination training alongside a traditional cardiac rehabilitation programme may improve static and dynamic balance, and muscle strength, skills that are considered major components in postural control. Clinicians who work in cardiac rehabilitation centres should consider including this training alongside the routine cardiac rehabilitation programme.

The Acute Effect of Exercise on Executive Function and Attention: Resistance Versus Aerobic Exercise.

Acute aerobic exercise was shown to enhance such cognitive functions as executive function (EF) and attention. Acute resistance exercise was also shown to enhance cognitive functions, however, only few studies directly compared these two exercise modalities. The aim of this study was to evaluate the acute effect of a typical moderate intensity resistance exercise session as compared to a typical moderate intensity aerobic session, on executive function and attention. A counterbalanced repeated measures experimental design was applied. Forty physical education students (21 women; 19 men, age = 25.7±2.84 years) were tested before and after three sessions: aerobic, resistance, and control. Each session consisted of 30 minutes of exercise or a rest. Executive function and attention were assessed by components of the computerized Stroop Catch game and Go-NoGo cognitive tests. A two-way ANOVA showed a greater increase in attention scores after the resistance sessions (p < .05) compared to the control condition. Attention scores in the aerobic sessions showed a trend toward improvement but did not reach statistical significance. Scores of EF significantly increased, both after the resistance session and the aerobic session (p < .05), but not after rest in the control condition. Our findings show that an acute session of resistance exercise increased both Attention and EF test scores, while an aerobic exercise session improved only the EF scores.

Postural control and posture-unrelated attention control in advanced age-An exploratory study.

OBJECTIVES: The link between postural control and cognition is under-studied, especially in healthy older adults. In the present study, we examined the link between postural control and posture-unrelated attention control. STUDY DESIGN AND OUTCOME MEASURES: Healthy individuals (n = 112) - men aged 77.2 ± 5.5, and two groups of women, aged 78.6 ± 3.5 and 68.9 ± 3.7 - participated in this cross-sectional study. Postural control was assessed by static balance (SB) posturography in eight standing positions, and by two measures of dynamic balance (DB): the Timed Up-and-Go (TUG) test, and the Functional Reach Test (FRT). Attention control (inhibition) was assessed by the Continuous Performance Test (CPT) measuring Go/NoGo tasks with and without visual and audio distractors. RESULTS: Men tended to perform better on DB and women on SB. In the men, significant correlations were observed between Go/NoGo tasks and DB (r range: 0.373 to 0.653 for TUG, and -0.342 to -0.530 for FRT). In the younger women, Go/NoGo tasks were correlated with SB (r range: 0.323 to 0.572), and no correlations were observed in the older women. Go/NoGo tasks without distractions followed by tasks with audio distractors explained postural control measures. CONCLUSIONS: Posture-unrelated attention inhibition was associated with SB in the women and with DB in the men. Tasks with no distractions explained the variability in postural control in both genders. It is recommended to examine the effect of balance exercises on postural control and posture-unrelated attention control in both genders, and the contribution of the relationship between postural control and posture-unrelated attention control to falls in old age.

Kinematic and Kinetic Analysis of Repeated and Static Elevé in Adolescent Female Dance Students.

Elevé is a fundamental dance movement practiced routinely by dance students and serving as an integral component of screening in dance. It consists of ankle plantar flexion (PF) movement and is considered to be a frequent cause of foot and ankle injuries among dancers, with adolescent female dance students being at greatest risk for such injuries. Therefore, gaining additional knowledge regarding elevé functional range of motion (ROM) and inter-leg weightbearing distribution (WBD) properties among adolescent dance students is warranted for pedagogic, screening, injury prevention, and rehabilitation purposes. The aims of this study were three-fold: 1. to report and compare dance-specific, functional kinematic (ankle PF maximum angle and ankle PF ROM), kinetic (inter-leg WBD), and self-reported level of difficulty (balance, muscular force, and concentration) properties of repeated and static elevé among adolescent female dance students; 2. to look for correlations between elevé properties and participants' demographics (age, height, weight, dance experience, and leg dominance); and 3. to describe the relationships between the two kinematic properties in both elevé tasks. Twenty-three adolescent female dance students (mean age 13.57 ± 0.50 years) were measured while performing two elevé tasks: 10 repetitions ("repeated elevé task") and 10 consecutive seconds hold ("static elevé task"). Data regarding ankle motion and WBD were collected and analyzed using three-dimensional motion capture and two force plates. The data gained from this study expand our current understanding of elevé dance movement and may contribute to clinical relevancy and applicability of screening procedures being conducted in pre-professional dance settings. This may help to identify adolescent dance students with the potential to undertake a career in professional dance as well as to investigate the parameters associated with risk of ankle injuries in this population.

Physical Activity-does it Really Increase Bone Density in Postmenopausal Women? A Review of Articles Published Between 2001-2016.

BACKGROUND: Physical activity is known for its many health benefits; among them being the positive effect on bone health during the life cycle. During childhood, physical stress stimulates bone remodeling and increases density. However, due to hormonal changes during adulthood, and mainly during postmenopause the rate of bone remodeling is slowed down and is less efficient. As a result, argument has arisen in the literature regarding the benefit or harm of physical activity on bone health among postmenopausal women. OBJECTIVE: The study aims to examine the efficacy of physical activity for improving Bone Mineral Density (BMD) in postmenopausal women based on a review of the literature. METHODS: The articles included in the review were chosen from three databases (PubMed, SPORT Discus with full text and Science Direct). Only publications with intervention studies which provided BMD measures clearly affected by physical activity in postmenopausal women were included. Twelve articles met the criteria for inclusion. RESULTS: In general, physical activity had a positive effect on BMD. Exercise prevented bone loss and in some cases, it contributed to the increase in BMD. CONCLUSION: Physical activity may improve BMD in postmenopausal women. However, the exact type of activity, its intensity, its duration and its frequency, are still unclear. Further studies are needed to determine the precise training protocol for postmenopausal women.

The Complex Association Between Fear of Falling and Mobility Limitation in Relation to Late-Life Falls: A SHARE-Based Analysis.

OBJECTIVE: This study examines fear of falling (FOF) in relation to falls in light of mobility limitation. METHOD: Data on community-dwelling older Europeans, aged 65+, were drawn from two consecutive waves of the Survey of Health, Ageing and Retirement in Europe (SHARE). The analysis regressed fall status in 2013 on reported FOF 2 to 3 years earlier, controlling for previous falls. RESULTS: FOF predicted subsequent falls when mobility limitation was low to moderate. However, the effect of FOF on fall probability was reversed when mobility limitation was high. DISCUSSION: The analysis underscores a complex association between FOF and mobility limitation in relation to late-life falls. People who are worried about falling tend to fall more. Those having high mobility limitation but lacking FOF are also more likely to fall. In cases of considerable mobility limitation, FOF may act as a protective buffer. The less worried in this group, however, may be subject to greater falling, and thus require greater attention.

Balance Performance Is Task Specific in Older Adults.

Balance ability among the elderly is a key component in the activities of daily living and is divided into two types: static and dynamic. For clinicians who wish to assess the risk of falling among their elderly patients, it is unclear if more than one type of balance test can be used to measure their balance impairment. In this study, we examined the association between static balance measures and two dynamic balance field tests. One hundred and twelve community-dwelling older adults (mean age 74.6) participated in the study. They underwent the Tetrax static postural assessment and then performed the Timed Up and Go (TUG) and the Functional Reach (FR) Test as dynamic balance tests. In general, low-moderate correlations were found between the two types of balance tests. For women, age and static balance parameters explained 28.1-40.4% of the variance of TUG scores and 14.6-24% of the variance of FR scores. For men, age and static balance parameters explained 9.5-31.2% of the variance of TUG scores and 23.9-41.7% of the variance of FR scores. Based on our findings, it is suggested that a combination of both static and dynamic tests be used for assessing postural balance ability.

Effect of a specialized injury prevention program on static balance, dynamic balance and kicking accuracy of young soccer players.

AIM: To study the effect of balance intervention program using the "FIFA 11+" program on static and dynamic balance and kicking accuracy of young soccer players. METHODS: Twenty young soccer players were allocated to experimental (n = 10) or control (n = 10) groups. The experimental group performed the "FIFA 11+" program three times a week for six weeks. The control group performed their normal warm-up routine. The primary outcomes were measured pre and post intervention, and assessed kicking accuracy, static balance and dynamic balance. RESULTS: No differences were found in kicking accuracy following intervention, for both groups, however, static balance improved significantly among the experimental group with significant interaction with the control group, and with high effect size. In addition, the dynamic balance of the left leg of the experimental group, with medium effect size for interaction between groups. CONCLUSION: The large effect size of balance improvement that was observed following six weeks of intervention sessions, implies that soccer trainers and coaches should consider the inclusion of "FIFA 11+" as components of programs aimed at improving balance ability/control in young soccer players, as improvement in balance abilities may prevent injuries.
